An Erp Investigation Of Reward Signals For Differing Classes Of Reinforcing Stimuli, Darin R. Brown

Psychology ETDs

In order to successfully traverse an actively complex environment, an agent is required to learn from the consequences of their actions. For over a century, models of behavior have been developed demonstrating these consequence-based learning systems. More recently, underlying biological systems have been found to adhere to these constructs of learning. The electroencephalographic signal known as the Reward Positivity (RewP) is thought to reflect a dopamine-dependent cortical signal specific to reward receipt. Importantly, this signal has been shown to adhere to an axiomatic (rule-like) positive reward prediction error, whereby it is evoked following outcomes that are better than expected. These …

Effects Of Perceived Audiences On Discrimination Learning In Pigeons ( Columbia Livia ), Peyton M. Mueller, Matthew Murphy

Honors Theses

The social facilitation effect is a phenomenon frequently discussed in the subfield of social psychology. Some studies have examined the social facilitation or inhibition effects in nonhuman animals, though few have examined the effect of perceived audiences on their cognitive functioning. In order to study this effect, three different video stimuli were presented to one subject while solving a memorization discrimination task. It was hypothesized that the pigeon would learn a task at different rates based on the type of perceived audience presented. No significant results were found due to the fact that the subject was unable to learn the …

A Meta-Analytic Review Of Cognitive Functioning In Negative And Positive Symptoms Of Schizophrenia, Tiffany Forsythe

Electronic Theses and Dissertations

The purpose of the study was to conduct two meta-analytic reviews examining cognitive functioning and schizophrenia. The first review examined the literature comparing the cognitive functioning of schizophrenic patients to healthy controls. A second review examined the cognitive functioning within schizophrenic patients, examining the differences between individuals with primarily positive symptomatology and those with primarily negative symptomatology. The first meta-analysis included 19 studies which assessed 861 schizophrenic patients and 858 healthy volunteers overall. The second meta-analysis included 10 studies comparing the cognitive functioning of 1,263 schizophrenics across positive and negative symptoms. Results of the first review indicated that healthy controls …

Developing Sensory Behavioral Assays For Zebrafish Autism Model, Shannon Wagner

Honors College Theses

Individuals of all ages can suffer from a wide variety of symptoms and disabilities that could be diagnosed as Autism Spectrum Disorder (ASD). Due to new methods and technology, individuals are now being diagnosed in the first two years of their life, which is when the signs of ASD are initially exhibited. Individuals diagnosed with ASD share many similar disabilities and symptoms such as hyperactivity to social, visual, and auditory stimuli, as well as hyposensitivity to olfactory stimuli. Neural circuit-based alterations are widely considered as a cause for these behavioral aberrations. We have created behavioral assays using zebrafish larvae to …

Its Skin Is My Skin, Bryan Page

Graduate School of Art Theses

This text examines the complexity of attempting to empathize with bodies that are vastly othered from my own. This broad yet nuanced subject crosses epistemological boundaries and complicates the dualities between both the mind and body, and between the corporeal and the virtual. My desire to better understand the conditions of another’s experience originates from a painful traumatic loss which caused me to feel isolated and incomplete. In response to this suffering, I long to emotionally connect with other beings and create artwork that attempts to bridge the qualia of individual experience.

I am interested in the capacity (or lack …

Ptsd Precipitating From Sexual Abuse And Combat War Exposure And Co-Morbid Disorders Of Chronic Pain, Substance Abuse And Immune Systems, Jessica Anzalone

Honors Program Theses and Projects

Posttraumatic stress disorder (PTSD) is a trauma and stress related disorder that some people develop after exposure to a traumatic life altering event. The person must witness the traumatic event, have the traumatic event occur to a loved one, or experience a traumatic event first hand. According to the publication of the American Psychiatric Association, the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the diagnostic criteria for the identity of PTSD must include behavioral symptoms that accompany PTSD in four diagnostic clusters; re-experiencing, avoidance, negative cognitions and mood, and arousal (American Psychological Association, 2018). Two …

The Relationship Between Psychological States And Health Perception In Individuals At Risk For Cardiovascular Disease, Kyoung Suk Lee, Frances J. Feltner, Alison L. Bailey, Terry A. Lennie, Misook L. Chung, Brittany L. Smalls, Donna L. Schuman, Debra K. Moser

Family and Community Medicine Faculty Publications

Backgrounds: Perceptions of health are important to motivate people to change behaviors. Non-adherence to healthy behaviors that prevent cardiovascular disease may result from inadequate health perceptions. However, there are few studies investigating relationships between health perceptions and psychological states.

Objective: To determine whether psychological states (ie, depressive symptoms and anxiety) are associated with the congruency between health perception and estimated risk for cardiovascular disease in adults with 2 or more cardiovascular disease risk factors.

Methods: Community dwellers at risk for cardiovascular disease were asked to complete the Patient Health Questionnaire-9 and the anxiety subscale of the Brief Symptom Inventory to …

Post Traumatic Slave Syndrome A Literature Review On African American Community Healing And Expressive Arts Therapy, Akinlana Burrowes

Expressive Therapies Capstone Theses

Post traumatic slave syndrome (PTSS) is defined as “a condition that exists when a population has experienced multigenerational trauma resulting from centuries of slavery and continues to experience oppression and institutionalized racism today.” Throughout this literature review, the physical, mental, and socioemotional impacts of institutionalized oppression through the years from the 1600s to the present, exhibited in the multiple sectors of society as it relates to the African American (AA) community are explored and addressed through the theoretical framework of PTSS. While a sizable body of literature has supported Expressive Arts Therapy (EAT) with traumatized populations, very little research has …

Back To Belonging: Nature Connection And Expressive Arts Therapy In The Treatment Of Trauma And Marginalization, Jesse Newcomb

Expressive Therapies Capstone Theses

There is increasing research on the benefits of incorporating nature-based approaches into mental health. This can be done in myriad ways both in and out of the counseling office. This literature review focuses on the benefits of incorporating nature as co-therapist and kin rather than only material or metaphor, particularly in the treatment of people who have experienced trauma and or marginalization. According to Herman (1997), wounds made relationally must be healed relationally, and the literature reviewed in this paper suggests that connection with the “more-than-human” world (Abram, 1996), and coming back into a sense belonging in the larger web …

Exploring The Adulthood Transition Through The Eyes Of Adults Living With Autism Spectrum Disorder: A Phenomenological Study Of Their Expectations, Perceptions, Experiences, And Goals Regarding Adulthood, Matthew Noakes

Senior Honors Theses

Autism spectrum disorder (ASD) is a prevalent developmental disorder that makes daily, independent living difficult for many people around the world. Depending on the severity of ASD symptoms, individuals living with ASD rely on various supports to develop everyday skills. However, many of these supports fade away as these individuals transition out of high school into adulthood where they are introduced to an entirely new set of social systems including postsecondary institutions, workplace environments, independent/codependent living arrangements, and mature social relationships. Four emerging adults with ASD were interviewed to gather their expectations, perceptions, experiences, and goals regarding these different domains …

Over Certain Undecidedness These Heartstring Intimations, Martha Hemingway

Senior Honors Projects, 2010-2019

over certain undecidedness these heartstring intimations is the culmination of a two-year-long abstracted cycle of textured conversation, internal eye contact, and endless playlist-making. Hemingway’s work is based in process-oriented reflections on habitual behavior, manifestation of sentiment, and sense of self. Her paintings draw inspiration from the ways in which we approach and avoid our internal and external routines – how degrees of our subconscious considerations affect how we extend ourselves to others. Individual auditory preferences of different colliding souls have carved a space for her in a language of empathetic abstraction – attempting to elaborate the curious beauty and pain …

Investigations Of Operant Aba Renewal During Differential Alternative Reinforcement, Ryan T. Kimball

Theses & Dissertations

Operant renewal is a form of relapse in which a previously extinguished response recurs due to a change in context. We designed two experiments to examine the impact of differential reinforcement of alternative behavior on ABA renewal in a translational model of relapse with 12 children either diagnosed with autism spectrum disorder, an intellectual disability, or who were neurotypical. We compared levels of renewal in two, three-phase arrangements. In one arrangement, we reinforced target responding in Context A, extinguished responding in Context B, and returned to Context A while continuing to implement extinction. In a second arrangement, an alternative response …

Developing A Multi-Dimensional Measure Of Growth Mindset For School Improvement, Thomas Hartka

Masters Theses, 2010-2019

The goal of the present study was to create a multi-dimensional growth mindset (MGM) measure. The purpose of the measure was to serve as an indicator of improvement for a team of 6^th grade Math teachers in a local Middle School. These teachers noted that while their students were showing stronger self-reported growth mindset beliefs following interventions, they were not consistently displaying improvement in growth mindset behaviors. Following deeper discussions with this team of teachers and review of the growth mindset literature, six dimensions of growth mindset were identified: (1) intelligence belief, (2) effort, (3) persistence, (4) mistakes, (5) …

Effects Of A Lag 3 Schedule Of Reinforcement On The Variability Of Tacting In Individuals Who Engage In Vocal Stereotypy, Jessica K. Serrao

Masters Theses, 2010-2019

Individuals with autism spectrum disorder (ASD) or other developmental disabilities may experience rigid or repetitive behaviors, known as stereotypy. Current research determines effective interventions for increasing variability of vocal responding which effectively decrease stereotypic vocal responding. Lag schedules of reinforcement are a common theme among variability of vocal responding research. The purpose of this AB design study was to evaluate the effectiveness of a Lag 3 schedule of reinforcement in the teaching of variability of tacting. Results indicated that both variable and novel responses increased after the implementation of the Lag 3 schedule, but since these results are based off …

Naloxone And Ethanol Addiction Reinforcement, Roland T. Smith Iii

Theses and Dissertations

A study was carried out examining how naloxone administered after high-incentive ethanol exposure can interrupt the reinforcing effect of drugs of abuse in C57BL/6 mice. Naloxone was shown to be an effective tool for blunting preferential and motivational behaviors associated with ethanol addiction.

Theses and Dissertations

Chimpanzee (Pan troglodytes) tracking is a popular ecotourism activity across Sub-Saharan Africa, offering visitors a personal wildlife experience. However, chimpanzee ecotourism may increase the risk of disease transmission between chimpanzees and people. This study assessed how tourist behaviors might facilitate cross-species disease transmission in Kibale National Park, Uganda.

Rapid Demand Curves: Reward Valuation Using Behavioral Economics, Charles Nastos

Masters Theses, 2010-2019

Within the past few decades, the psychological field of operant behaviorism has converged with the field of economics to aid in the description and interpretation of behavior. In doing so, more stringent, empirical methods of measuring and analyzing behavior have been produced. Laboratory experiments with both human and non-human animals have been used to study concepts that are integral to both fields, such as supply and demand, scarcity, and choice behavior. One goal of behavioral-economic research is to establish a demand function; that is, how does a change in the price of a commodity influence changes in its consumption? Consequently, …

Using An Eye-Tracking Training Paradigm To Teach Responsiveness To Joint Attention, Allison C. Brandmark

Masters Theses, 2010-2019

Joint Attention (JA) is a social interaction in which attention is concurrently managed between an object or event and a social partner. One social partner initiates joint attention (IJA) by directing the attention of the other social partner. In return, the other social partner responds to joint attention (RJA) by following the social cues. A deficit in JA, which is commonly seen in children with Autism Spectrum Disorder, is correlated with delayed language development and lower levels of communication and social skills. Several studies have successfully trained both IJA and RJA using in-person methodologies. With the development of new technology, …

Using Video-Prompting And Bst To Promote Social Skills In Children With Autism Spectrum Disorder, Alexa Ina

Masters Theses, 2010-2019

The purpose of the present study was to examine the effectiveness of implementing a combined and integrative Behavior Skills Training (BST) and video-prompting paradigm. The training focused on enhancing social interactions and fostering the development of age-appropriate social skills in children diagnosed with Autism Spectrum Disorder (ASD). This package included explicit training for generalization, as a means of fostering skill acquisition across untrained people and settings. Social initiation and reciprocal play are fundamental aspects of sustaining and maintaining relationships therefore, the training focused on teaching these two behaviors. The researcher used a quasi-single subject research design to analyze and measure …

The Effects Of Adenosine Antagonists On Vigilant Attention In Sleep Restricted Rats, Morgan Crewe

Masters Theses, 2010-2019

The relation between chronic sleep restriction and performance on the Psychomotor Vigilance Task (PVT) have been well documented in the human literature, with chronic sleep restriction as little as 7 hours per night resulting in significant impairment in sustained attention performance measured via the PVT. Recently, an analogous version of the human PVT has been developed for use with rodent models (rPVT). Recent studies have measured the effects of sleep restriction on rPVT performance, citing similar results found in the human literature. However, few studies to date have directly examined the role of adenosine accumulation during sleep deprivation in producing …

Attachment In Middle Childhood Among Foster And Adopted Children: Preliminary Validation Of A Behavioral Observation System, Somer George

Dissertations, 2014-2019

Abstract

The study of attachment in middle childhood, especially among foster and adoptive children, is a critical and timely one. An assessment that helps us understand the behavioral manifestations of attachment for these children, while considering the link with caregiving behavior and parental reflective functioning (PRF) can help to provide effective and efficient intervention leading to security and relational healing. This study examines the attachment patterns of 39 foster and adopted children (ages six to twelve) in the Modified Strange Situation Procedure (MSSP), with their caregivers. Association with caregiving patterns, PRF, and caregiver reported child behavior are analyzed using Pearson’s …

“Flowing Along The Wall”: Anarcha-Feminist Bioethics And Resistance In Octavia E. Butler’S Dawn 2019., Theresa Mendez

Master's Theses

Science fiction (sf) texts conversant with the temporal play between past, present, and future push readers to imagine the extremes of human and environmental existence, interaction, and potential. Simultaneously, despite the sf genre’s tendency to traffic in extremes, these texts provoke readers to consider the ways in which these imagined worlds are grounded in history as well as in the contemporary social moment. As Donna Haraway has argued, “the boundary between science fiction and social reality is an optical illusion” (306). This illusory boundary must continue to be traversed in order to consider how sf literatures, particularly those which imagine …

Developmental Changes In Reasoning About Cross-Classified Individuals., Catherine H. Mcdermott

Electronic Theses and Dissertations

Social categories allow children to make inferences about novel situations, which can then guide their interactions with others. However, this process can be complicated because individuals often belong to many different, sometimes interrelated, social categories. Four experiments examine whether children and adults differ in their willingness to classify a person as holding two social roles (e.g., a mother and a daughter), and how this influences their reasoning. Specifically, this work will examine the influence of cross-classification on inductive inferences, trust in testimony, and knowledge evaluations. The aim of these experiments is to investigate whether children privilege certain roles when reasoning …

Trends In Advanced Hiv Disease And Long-Term Outcomes Of Hivinfected Children Treated With Antiretroviral Therapy In Eastern And Southern Africa: 2003-2017, Peter James Elyanu

Dissertations and Theses (Open Access)

Despite the over 10-years’ experience providing pediatric antiretroviral therapy(ART) and implementing different WHO guidelines, data on updated trends (after 2010) in advanced disease at ART start, and on long-term survival of children receiving ART are scarce. Without these data, the impact of recent WHO guidelines on early treatment initiation and long-term survival remains unclear. First, we examined trends in advanced disease at ART start, then described 10-year survival and investigated risk factors of early mortality in children treated with ART and lastly examined the association between rapid ART initiation and outcomes (mortality and loss to follow-up) of HIV infected. We …

The Effects Of Temporal Contraction And Temporal Dilation On Cognitive Performance, Amandeep Singh Dhaliwal

Psychology Theses - Archive

Temporal dilation and temporal contraction are perceived as duration lasting longer or shorter than the standard time unit, respectively. Social, cognitive, and emotional context influences temporal perception such that socially stressful or cognitively demanding tasks distort the perception of time. In the present study, subjects (N = 123) first experienced a state of mindfulness, reported to cause temporal dilation (Kramer et al., 2013) and then performed a demanding cognitive task, reported to cause temporal contraction (Block et al., 2010). Subjects watched either a guided mindfulness video (experimental) or a relaxing music video (control). Subjects then estimated the duration of the …

Effects Of Skin Color And Clothing Color On Perceived Violence And Aggression Of Criminals, Courtney Merchant

USC Aiken Psychology Theses

Introduction: Society has a history of attaching meaning to colors, and few colors have been given as much attention as red and black. In many contexts, these colors have strong negative associations. Red has long been representative of danger and aggression (Young, Elliot, Feltman, & Ambady, 2013), while black represents death and evil (Adams & Osgood, 1973; Sherman & Clore, 2009). Unfortunately, color associations are not limited to clothing or advertisements; skin color is also a subject of negative associations in the form of stereotyping. Darker skinned people, especially African-Americans, have long been subjected to negative stereotypes. The current …

Ethical Art Waste: Examining Resource Management In The Art Studio, Amanda Peavey

Expressive Therapies Capstone Theses

This paper highlights the lack of education about production and disposal of art materials within the field of art therapy. Failure to educate clinicians creates ethical problems when hazardous materials are used in sessions unknowingly. This paper is grounded in environmental studies and chemical management to supplement the art therapy field’s lack of research and commentary. The literature is dedicated to educating the reader about the hazardous nature of materials, issues surrounding regulations of chemicals involved in production, and consumerism in relation to waste processing. The research data was collected from a community engagement project: an educational presentation was offered …

The Need To Believe: Belief In Science & Religious Belief Examined As More General Components Of Positive Psychological Functioning, Jordan Madrigal

Honors Theses

Furthered by the spectacular innovations of technological advancement over the recent centuries, empirical science has yielded a depth of knowledge about the universe that early naturalistic philosophers could not imagine. Present-day scientists seem to have a much stronger motivation to espouse naturalistic worldviews than do early philosophers – the explanatory power of science appears to render null the need for explanations via numinous religious beliefs. Why do so many people maintain religious beliefs, then? A large body of literature suggests that religious belief is strongly associated with positive psychological functioning. However, other research suggests that religious belief is sometimes associated …
